What exactly happens if I pick a new winner for my Giveaway that finished?

You have 7 days to deliver the gift. And why don't you want to email it?

You get spanking. spank spank

No you have to keep trying for 7 days, sorry.

I think you have to wait 7 days and if user does not respond then you have the right to pick a new winner.
Please correct me if i'm wrong.

Also didnt your giveaway just enter 17 minutes ago

Since you guys live in opposite timezones, you'll have to take a leap of faith and send it through mail. Even if the guy lived in your same city, he could still work the night shift. It seems a bit unfair to just just reroll.
When in doubt, ask a mod.

If you are afraid, for the future you could try a private giveaway with a special rule for timezones (if it gets approved by a mod first). :)

Here is how it works:

1) You wait seven (7) days.
2) If, after seven days, you have been unable to contact the guy, you request a re-roll of the giveaway from Support.
3) Support will ask you for evidence that you have tried to contact the winner. Provide them with screenshots and/or emails.
4) Support will see that you tried to get in touch with the guy and will re-roll the winner.
5) Now, try and contact the new winner.

Example: I had a winner who was offline for about two weeks. I sent Support screenshots of my attempts to contact him and his login history. They re-rolled it, and I gave the game to the new winner.
